Biopsychosocial correlates of body satisfaction in 7- to 8-year old children: a cross-sectional and prospective investigation.

Background: Biopsychosocial factors have been associated with body satisfaction/dissatisfaction and related body image concerns in adolescence; however, few studies have investigated these relationships in middle childhood, an important developmental phase for body satisfaction. This study investigated relationships between a range of biological (body mass index), psychological (child anxiety/depression, self-esteem, and self-oriented and socially prescribed perfectionism) and sociocultural (mother's body dissatisfaction and comments about child's appearance, father's body dissatisfaction and comments about child's appearance, peer teasing and child's media exposure) factors and body satisfaction cross-sectionally and longitudinally in a sample of 7- and 8-year-old children.

Methods: In this study, participants from the longitudinal Children's Body Image Development Study (in which children had been followed-up annually from 3 years old) were assessed by interview at 7 years old (Time 1; n = 293: girls = 167, boys = 126) and 8 years old (Time 2; n = 222; girls = 126, boys = 96) and their parents completed a questionnaire at each time point.

Effects of voice enhancement technology and relaxing music on the frequency of imagery among break dancers.

A device was developed in 2008 by Hypnoke International Ltd. for use by performance consultants and hypnotherapists. It enhances a practitioner's voice and blocks out auditory distractions while delivering imagery inductions, thereby increasing their effectiveness.

Exosome release of β-catenin: a novel mechanism that antagonizes Wnt signaling.

CD82 and CD9 are tetraspanin membrane proteins that can function as suppressors of tumor metastasis. Expression of CD9 and CD82 in transfected cells strongly suppresses β-catenin-mediated Wnt signaling activity and induces a significant decrease in β-catenin protein levels. Inhibition of Wnt/β-catenin signaling is independent of glycogen synthase kinase-3β and of the proteasome- and lysosome-mediated protein degradation pathways.
